To minimize drift, you should aim for which spray droplet size?

• A. Fine droplets
• B. Coarse droplets
• C. Medium droplets
• D. Very fine droplets

Answer: (B)

Droplet size is a key factor in spray drift: smaller droplets are carried by air currents longer and can travel far from the target, while larger droplets are heavier and settle to the ground more quickly. Coarse droplets strike a good balance because they are large enough to resist being blown off target, reducing drift potential, yet still provide effective coverage when applied with proper technique. Very fine and fine droplets drift much more easily, and medium droplets are somewhere in between. By aiming for coarse droplets, you minimize off-target movement while still achieving the intended pest control, especially when combined with appropriate nozzle type, pressure, and application conditions.
